Estimation of flight altitude in the aperture synthesizing mode for altimeter with continuous probing signal

Mikhail Yu. Nesterov, Andrei A. Monakov


It is proposed the function, defining phase modification of point, ground located reflector at the aperture synthesizing interval of radar altimeter with continuous LFM signal. It is carried our general function shape in wave domain and its expansion by “fast” time. We synthesized the algorithm of the altitude estimation, taking into account the carrier movement during process of beating signal shape. There are represented the results of full-scale experiment.
